Today I have installed the Pic-a-Pix app on my iPod Touch (G2). I have two problems: (1) The red cursor stutters. (2) Some lines are drawn incorrectly, namely the thick ones: They are not drawn completely (partly thick, partly thin).

Maybe you say regarding problem 1 that my iPod is too old. Ok. But what about the lines? The thick lines are necessary to keep track and thus are very important.
